Hi Roy, could this be the beastie? https://jyetech.com/dso-138-oscilloscope-diy-kit/ Cheers, John VK4ATU

Sight unseen, could the BNC be a reverse BNC? One where the nominal female has a male stinger? I've ran into them in the oddest places. The FCC requires reverse BNCs, TNCs, and SMAs on WiFi

I was given this little thing a while back, haven't done anything with it yet... There's this board, no particular identifying marks on just what it is. The oddest BNC I've ever seen on top, some

Sound's like a great way to go!. You may find it a easier go to start with Microchips evaluation kit for the AVR-1 product...it will greatly speed your development time by relieving you of tedious

After much research looking at "single momentary input toggle output" latches based on the 74hc74, inverters, 2In Nand, mosfet / bjt, and variations of other flip flops, I have decided using gates for

Hello, I am using this mixer as a phase detector in a PLL? used? in down converting. I got a matlab plot of the Error voltage as a function of frequency(A and B pint in the diagram). from this error

In my situation, just about the time I was ready to order an analyzer software package the company came out with V2.0 drivers which solved the problem.

Have you looked at that little analyzer that I mentioned a while back? Check out sigrok.org, the thing cost me under $20 and has a *LOT* of different protocols that the software (pulseview)

Yes. It does. That photo tells me that what I am trying to work with is a HighSpeed cable, and that what I need is a simple standard cable. That photo is exactly the same as the cable I am working

Ah USB 3 has the same 4 wires as USB 1 & 2 plus 4 extra ie 2 twisted pairs, sort of thing used for differential and screened too ie very high speed.

Ken: Does this help? Look at the fifth image <https://www.amazon.com/URWOOW-SuperSpeed-Extension-Convertor-Extender/dp/B083TGBMR4> in the description. [image: image.png] -- *G.T.* -- *G.T.*

I meant to add, are you sure you have genuine USB chips? There are a lot and I mean many counterfeits on the market that almost work right. Look up USB FTDI fake or counterfeit.chips. The fakes can

Can't answer the first question but as for the second. Monitor the output with a spectrum analyzer, take care to protect input! Increase drive level until more drive doesn't cause a corresponding

Hello,I have the following old mixer called TXF-18075 which I want to test for saturation and power levels in down converting mode. I dont have any datasheet only this brief table I found.Unlike
